Seeing People and Knowing You: Perception, Shared Knowledge, and Acknowledgment

This article takes up the proposal that action and expression enable perceptual knowledge of other minds, a proposal that runs counter to a tradition of thinking that other minds are special in that they are essentially unobservable. I argue that even if we accept this proposal regarding perceptual knowledge, there is still a difference between knowing another person and knowing other things. I articulate this difference by pointing out that I can know another person by sharing knowledge with her. Such sharing is expressed in the use of the second-person pronoun. Thus, I argue, other minds are indeed special as objects of knowledge, but not in the way the tradition has supposed.
